TWSBI ECO fountain pens have stainless steel nibs and use a piston filling system. The barrels are clear so you can see the amount of ink and the cap includes an inner cap that provides a perfect seal when the pen is not in use.
Note: Please take care if removing/adding the nib as it is very fragile.
How to Choose a Nib Size:
- If you write small, go with Extra-Fine
- For everyday use, Fine is a great choice
- If you tend to write on the larger size, Medium is perfect and does provide a smoother ink flow
- Bold is for statements - Sign a check, write a header or show off your shimmering/sheening ink
- Stub nibs are used for an italic/calligraphy writing style with the down strokes being wide and the side strokes thin.\
